Abstract (en)
[origin: EP0408932A2] The locking device for an adjustable vehicle seat has a locking rail (22) which runs parallel to an adjustment direction (20) and has periodically arranged catches (24) and catch openings (26) and a locking unit assigned thereto, which unit has two locking teeth (30, 32) which have in each case two lateral edges which can be moved independently of one another in an engagement direction (40), are elastically prestressed, can be disengaged together, are arranged at a distance z from one another and are intended to rest against the catches (24). At least two locking teeth (30, 32) are provided, in which at least one of the two lateral edges extends linearly and at an acute angle to the engagement direction (40), the angle being selected on the one hand to be as large as possible but on the other hand to be still sufficiently small that the locking tooth cannot be automatically forced out of its catch position when the vehicle seat is loaded in the adjustment direction (20). The sum of the projections of all the edges (42) which point in the same direction onto the adjustment direction (22) is not smaller than the period measure (P) of the catches (24) and catch openings (26). The locking teeth (30, 32 et seq.) are arranged distributed over at least one, preferably two, period measures P of the catches and catch openings in such a way that each catch tooth (30, 32 et seq.) has associated with it a different unit of the period measure P and the projection of all the edges (42) which point in the same direction onto the adjustment direction is not smaller than the period measure P. <IMAGE>
